Abstract

A method for manufacturing polyacrylonitrile-based precursor fiber used in production of carbon fiber, comprising spinning a raw spinning solution which contains a polyacrylonitrile-based polymer with a intrinsic viscosity of 2.0 to 10.0 and has concentration of said polyacrylonitrile-based polymer from 10 to 25 wt.%, by wet spinning process or wet-dry spinning process, and subjecting to steam elongation after dry heat treatment, wherein the linear rate of discharging said polyacrylonitrile-based polymer from spinning nozzle is 2 to 15 m/min. A carbon fiber provided by sintering the polyacrylonitrile-based precursor used in production of carbon fiber manufactured by said method, of which the strand tensile elasticity rate is 320 to 380 GPa, and the conductive electron amount determined by electron spin resonance is 3.0x1019 to 7.0x1019 spin/g.
